ABSTRACT:
A method is provided for optical amplification using a silicon (Si) nanocrystal embedded silicon oxide (SiOx) waveguide. The method provides a Si nanocrystal embedded SiOx waveguide, where x is less than 2, having a quantum efficiency of greater than 10%. An optical input signal is supplied to the Si nanocrystal embedded SiOx waveguide, having a first power at a first wavelength in the range of 700 to 950 nm. The Si nanocrystal embedded SiOx waveguide is pumped with an optical source having a second power at a second wavelength in a range of 250 to 550 nm. As a result, an optical output signal having a third power is generated, greater than the first power, at the first wavelength. In one aspect, the third power increases in response to the length of the waveguide strip.
